one or a plural number of webs of paperusually comprising preprinted forms as bills of lading, sales slipsand the like are supported, and in a superposed arrangement for manifolding, fed over a writing-table,.

for exposure within a margin frame area and to be withdrawn from the machlne and severed as to their form lengths. The paper,

used in the machine has apertures or perforations alined longitudinally in'a spaced relation, the degrees of spacing representing or corresponding to the measured sheet or form lengths and are also provided in pairs or plural number alined cross-wise of the strip. The apertures are utilized as indexes for strip cooperation with intercepting devices arranged to engage through the apertures when brought into register therewith automatically determining the length of paper withdrawal. The intercepting devices when engaged through the apertures are also utilized for feeding or withdrawing the strip from the machine sufliciently for manually grasping to be followed by a manual withdrawal until arrested by the intercepting devices. The intercepting devices when operating as feeding means receive their motion from the crank handle mounted external of the machinei rotating cam devices which operate and control the intercepting devices for moving the same in a forward .or paper feeding direction when engaged with the paper, releasing their paper engagement for a restoration of the arts for a subsequent operation leaving the intercepting elements as detents free to engage through the apertures in the paper when brought into alinement therewith. The mechanism provides for aquick and convenient manipulation, without careful observation in extracting or withdrawing the paper in determined or measured sheet lengths and leave a successive portion of the Web appropriately over the Writing table for its proper exposure within the margin frame, restrained against displacement;

Specification of Letters Patent.

The crank handle Patented Mar. 9, 1920.

"alining and registering the webs when several are employed for manifolding purposes, with respect to each other and to the parts of the machine, and a withdrawn portion. of the paper can be severed across a tearing blade without disturbing that portion of the web over the writing table.

The invention therefore, has as-an object to provide a member movable in a direction to and fro corresponding to the longitudinal feeding or withdrawing direction of motion of the paper over the writing table of the machine, said member carrying fingers or detents yieldingly urged to move transversely through apertures in the paper when the apertures are brought into registry withdrawal or movement over the writing table alining and registering the webs with relation to each other'and further for pro- Viding a connection or en agement with the paper for withdrawing the same when the detents are moved in a paper feeding direction or transversely to their aperture engaging motion. 'And,in providing means for controlling and operating "said detents.

The various features and objects of the invention will be more fully revealed in the description of the accompanying drawing, illustrating a preferred embodiment of the invention, forming apart of the specification, and in the drawings. like characters I therewith, as a stop or barrier against paper of reference denote corresponding parts throughout the several views;

ters the description'will beconfined to such class of machines and to the simplest form or type of machine in that class. The machines usually are loaded with several webs of paper arranged in a superposed relation over the writing table with a sheet of ink or carbon paper interposed between the web for manifolding, although some instances of use may only require a single web and the operation of the machine is equally as ellicient, either with one or a plural number of webs. In operating upon a plural number of webs with each comprising, say, duplicate printed forms, in which it is essential that the forms be alined and register one over the other for accurate manifolding results, the detent or intercepting means when entering the apertures in the paper function to correct any slight inaccuracies in the registration between the web portions over the writing table. As heretofore stated and as shown in Fig. 8, the paper longitudinally is provided with alined apertures definitely spaced, the degrees of spacing usually coordinate to a measured or determined sheet or form length and disposed within divisional blank spacing separating the forms successively. The paper is apertured or perforated at the time of printing and thus the apertures are very accurately located with respect to the printing and-as the intercepting means or detents function with reference to the lengthof strip between the perforation and also in relation to the web position and registry over the writing table, the paper is always brought and arrested for a proper form exposure defined as to its area by the margin frame over the writing table.

Referring to the drawings, 1 and 2 indicate a pair of side frames, which may be of-- sectional form, forming a carrier, one section hingedly mounted upon a second, with the opposite forward companion sections of both frames connected as a unit and adapted to be swung for convenient access into the interior of the casing. The side frames, oppositely, are provided with supports for journaling the webs of paper under a proper degree of tension. A writing table 3 is secured upon and supported 'between the side frames over which the from the machine. The parts of the machine just described are common to machines of this class and thus may represent a commercial type of construction.

The forward end of the margin frame is bent acutely upward to form a flange 5, reinforcing such margin frame end and providing an inclined support for the'tearing blade 6, which is fixed to the flange. The cutting edge of blade is at an elevation slightly above the writing table to clear the paper and not interfere with the paper with drawal. The margin frame as above stated is suitably locked or maintained rigid which is necessary when tearing the paper, in an upward action, across the edge of a knife.

A swinging carrier 7, in the form of a plate, is hingedly mounted upon a rod 8, i

opposite end to the carrier providing the proper tension for automatically returning the carrier to its normal position and maintains the carrier yieldingly against its cam actuator, A detent carrying plate 10 is slidably mounted upon the carrier 7 by screws 12 engaged into the carrier plate 7 each through an elongated slot in the plate 10. (See Figs. .6 and 7 The plate 10 sliding or reciprocating upon the plate in a plane parallel to said plate 7 is yieldingly'urged upwardly by the spring l313, fixed to the carrier plate 7 and detent plate 10. The plate 10 is provided with two pins or detents I l-+14 projecting from its upper end and relatively spaced, in degrees corresponding to the spacing of the crosswise alined apertures or perforations in the paper. Each deten-t'is adapted in an upward motion to engage through a respective oblong slot 15 in the Writing table 3 and through i-a registering oblong slot 16 in the margin frame 4. The detents for a paper feeding or withdrawing operation are depressed or retracted to bring them below the table plane out of the path of the traveling paper, such operation in the instance herein taking place after the paper has been withdrawn slightly or projected beyond the knife edge of the tearing blade, which places the paper aper: tures beyond a registering reach of the detents in their normal position, and in their normal position the detents are free to engage against the non-perforated under surface of the paper and automatically enter or snap through a succeeding set of apertures when brought into registry therewith. The

detents in entering ,the apertures in the paper exert a drawing influence on the several webs, if theirapertures are not in absolute register with the detents, alining the webs with respect to each other and machine parts and when the detents are engaged through the paper confines the paper against flush with the knife edge and impossible to grasp for a subsequent withdrawal. Imparting a forward motiori to the detents when engaged through the paper, the paper is drawn therewith bringing its end beyond the tearing blade. Such detent motion results from swinging the carrier forward a slight distance suflicient to extract the paper for manual grasping. To swing the carrier 7 I provide a shaft 17 extended to journal in the side frames, with one end thereof projecting externally beyond one of the side frames to receive a handle 18 which is fixed to the shaft. (See Figs. 5 and 6.) A cam 19 of a particular outline is fixed upon the shaft 17, (see Fig. 3), the periphery of the cam engaging the carrier moving the carrier forward in each revolution. A portion of the cam surface as at 20, is concentric with its axis and when engaging with the carrier ddes not influence the carrier, providing a dormant period for the carrier in its outermost position during which the detents are retracted or disengaged from the paper and retained in such retracted position until the parts are returned to their normal position.

The cam 19 engages the plate '3' through a slot 22 in the plate 10 and the slot provides a shoulder or abutment in the plate 10 adapted to be engaged by the cam for depressing the detents. The plate 10 at such cam engaging shoulder is provided with ,a project-- ing cross-lug 23 as a' shoulder extension, preventing the detents from being released by the cam or before the carrier has been returned and locked in its normal position.

Zlhe releasing moment of the detent carrying plate in the construction shown is after the carrier plate has been restored and locked in its normal position bringing the detents at right angles to the table, preventing them from interfering with the carrier return through possible engagement with the traveling paper. A lat-ch member 24: is supported and swiveled upon the cross rod 25 and as a bell crank, provides two arms projecting at right angles to each other, one as a latch arm projecting to engage through a slot 26 in the carrier plate, and notched to provide a shoulder for engaging said plate 7, locking said plate in its normal position,

' and of an extended length beyond the shoulder to confine the arm withinthe notch in the carrier plate at the forward .limit of carrier motion. The latch arm is released by a cam finger 27 fixed upon the'shaft 17 engaging the latch arm 28, and in a timed relation with respect to the cam 19 in each shaft revolution to raise the latch arm from its engagement with the carrier plate, before the carrier plate moves outwardly for apaper feeding or withdrawing operation. The latch moves by gravity into its carrier locking position after the carrier has been restored to its normal position. With the carrier normally locked against motion, the

detents likewise are held rigid against counter motion or motion in an are or transverse to their paper lnterceptmg motion so as not to be influenced by the motion of the paper as it is being withdrawn which would disturb their paper intercepting position.

Motion stop devices are provided for preventing reverse motion of the shaft 17 said devices comprising a flexible pawl blade 30, fixed to the side frame of themachine and projected to engage with the ratchet teeth formed on the end of the crank handle hub 31. 'The shank portion of the crank handle is flexible and tensioned inwardly toward the side frame so as to engage with a rigid stop block 32 projecting from the s1de frame, (see Fig. 2), limiting the free rotation of the crank handle to a single revolution and. requiring the shank to be flexed outwardly, to free itfrom the stop for a subsequent cycle. Various forms of motion stop devices, well known in the art, may be employed in lieu of that shown for continuous direction cycle operations and so contemplated within the concept of this invention.
